I saw something interesting about the AC systems on hybrids and electric vehicles a couple of weeks ago, I think it was on one of Scotties YouTube videos but I can't remember for sure.
The AC on hybrids and electric vehicles has a compressor that shares it oil with an electric motor that drives it. If the AC system of a hybrid or electric vehicle is serviced using a refrigerant drain and charge system that has previously been used to service an AC system on a conventional gas powered vehicle then a small amount of impurities from the small amount of oil that got into the drain and charge system from it being used on a conventional system will contaminate the oil in the compressor and electric motor so that the oil no longer is non-conductive. This caused the electric motor to short out and fail.
